GAS-LIGHTING FIXTURE.

nPhiladelphia and State of Pennsylvania,

have invented certain new and useful Improvements 1n Gas-Llghting F lxtures, of

. which the following is a specification.

Main burners and pilot lights have been used in association with a gas valve or gas valves but they possess the defect that in lighting" one by the other the pilot light is frequently accidentally extinguished especially where the gas valve or valves are operated quickly as is likely to be the case. In consequence the custom is to permit the pilot light to burn while the main burner is lighted as well as while the main 'burner is extinguished, so that a considerable quantity of gas is unnecessarily consumed by the pilot lights and this unnecessary consump- Vtion of gas by the pilot lights in connection with a large number of fixtures amounts to a considerable waste and loss.

The principal object of the present invention is to guard against or prevent accidental extinguishment `of the pilot light or lights when the gas controller is operated even rapidly for the lighting or extinguish.- ing of the main 'burner or burners and so to provide for satisfactorily extinguishing the pilot lightor lights when the main burner or burners are lighted and for relighting the pilot light or lights when the main burner or burners are extinguished without danger of accidental extinguishment of the pilot light or lights even though the controlling valve or valves be worked quickly or snapped as it is sometimes called.

Generally stated, the invention comprises the combination in a gas lighting fixture of a pilotlight or burner supply and a gas reservoir in communication therewith which operates to momentarily supply the pilot light supply when the gas valve or controller is in motion. The invention further comprises the improvements to be presently described and finally claimed.

In the accompanying drawings there is shown a view, principally in central section, illustrating one embodiment, chosen from among other embodiments, of the invention for the sake of illustration. i

In the drawings 1, is a pilot light supply,

l and 2, is a gas reservoir in 'communication with it. These elements are so combined that the reservoir 2, receives a supply of gas and gives it to the pilot light supply l, at a time when such additional supply is needed to keep the pilot light burning which is when the main burner is being lighted or extinguished. 3, is a valve casing having a gas inlet 4, a main burner outlet 5, a pilot burner outlet 6, and a gas reservoir outlet 7 8, is a plug valve mounted in the casing 3, and turnable for a part of a revolution as by means of 'the levers' 9, connected with; it. This valve has gas passages that coperate with the various inlets and outlets of the val-ve casing 3. As shown in tl e drawings the passage l0, is alincd with the gas inlet 4, and the main burner outlet 5, and so gas is supplied to the main burner and is not supplied to the pilot light; the latter is therefore extinguished and the former is burning. The pilot light supply 1, is connected with the pilot burner outlet 6, by a pipe or passage 11, and with the gas reservoir outlet by a pipe or passage 12. The yreservoir 2, is also connected with the gas reservoir outlet 7, as by a passage 13. 141a is a regulator byl means of which the size of the pilot light is regulated and xed. To extinguish the main burner the valve plug 8, is turned in the direction indicated by the dotted arrow. The result of this is that the passage 14, of the plug in passing the outlet 7, brings the latter into communication with the gas inlet et, so that the reservoir 2, is certainly filled with gas. The continued turning of the plug brings the passages 10, and 14, out of communication with the inlet fl, and so the main burner is extinguished. The continued turning of the plug brings the passages 16 and 15 into communication with the inlet 4, and pilot burner 6. It is during this turning motion of the plug that the reservoir by way of the connections 13 and 12. maintains a gas supply at the pilot light supply l, suiiicient for keeping the pilot burner alight even though the plug be turned rapidly. When the plug 8, is turned in a reverse direction its gas passages are connected up in the same way as has been described but in reverse order and the reservoir 2, receives its supply of .gas and gives it 0E to the pilot light supply. When the pilot light is burning, gas may lindits way at all times to the reservoir 2, b way the connection 12. 17, is a valve shown in open position ,although to correspond with the position of the plug 8, it would be closed,

the purpose being to illustrate details) that.

may be interposed, if desired, in the passage 13, which is provided with a seat 13, notched at 18. The valve 17, is guided by its stem 19, working through a spider 20, and Aby fingers 21, working on the outside of the valve seat 13a. The purpose of this valve, when present, is to permit gas to rapidly enter the reservoir and to slowly leave the same. By showing an inverted burner fitting I do not confine the invention thereto.

*What I claim is:

1. In a gas li hting fixture the combina.`

tion opa pilot urner supply, a gas reservoir in communication therewith, and ya quick opening check valve for the reservoir, substantially as described.

2. The combination in a gas lighting lixture of a pilot light, a main burner, a reservoir in communication with the pilot light, and asingle gas valve having two positions one for establishin the main burner supply and dis-establis ing the pilot light Supply, and the other for dis-establishing the main burner supply and for establishing the pilot light supply and said valve provided with a coperating port and gasy way for causing gas to momentarily enter the reservoir as the valve is moved from one position to the other to permit the reservoir to temporarily sustain the lpilot light.
